The AV130/Pro Mount Mini is a precision compact camera gimbal solution designed and manufactured by PhotoHigher for lightweight setups; no heavy lifter required. This small precision mount is an exact copy of the larger Pro Mount, only half the weight (320 grams), and is primarily suited to compacts, the new emerging mirror-less DSLR market and smaller professional imaging devices. Its internal dimensions allow for a DSLR up to a Canon 550D. PhotoHigher has done another exceptional job with this mount. It is constructed from lightweight alloys and machined engineering plastics and has a 2.5:1 reduction on tilt and a 8:1 reduction on roll. The tilt is powered by a digital programmable servo and an external 180 degree potentiometer and it has an external 10 turn potentiometer on roll powered by a digital high speed servo. Specifically designed for Droidworx to fit the AD-standard landing gear and gear rail assemblies.
